Behavioural Diversity in Groups of Juvenile Pigs
Individual differences in pig behaviour may be strategies of coping with a challenging environment. Pig performance varies and this may be related to individual behavioural characteristics. Three main factors were identified regarding personality. These included responses to social displacement activities, response to humans and moving...
Sequential Analysis of Belly Nosing of Early Weaned Pigs
Belly nosing has increased since implementing segregated early weaning in order to improve disease control and performance. To investigate how to decrease this behaviour, motivation behind belly nosing was monitored on pigs 7 days after weaning. Pigs who spend more time lying and eating participated...
Effect of Feed Presentation on the Feeding Behaviour of Grower-Finisher Pigs
The eating speed of pigs should be correlated with the maximum number of pigs to be fed from a single feeder. Competition, feed type, pig size and presentation of feed all influence feeding behaviour of pigs. Dry mash diets prolong feeding times, though this can...
Dietary Factors Influencing Water Consumption
Water is required in greater amounts than any nutrient and is necessary to biological functioning. Reducing water consumption and wastage will help reduce some environmental concerns such as pollution and groundwater stores and decrease costs of storing, spreading and hauling manure. As feed intake increases,...
New Method to Determine Barley DE is Indicative of Performance
Current measurement of grain DE content prevents voluntary feed intake measurements and does not reflect practical conditions. Unrestricted access to nutrient-adequate diets is a proposed method to investigate the DE content of barley. This may be a new method to evaluate feedstuffs true nutritional value....
Micronized and Flaked Wheat in Nursery Diets
Micronization and flaking are processes that increase digestibility in young pigs. This is especially true when regarding early weaned pigs, as endogenous enzymatic secretion is not quite established so micronized grains should be beneficial. These processes lead to faster weight gain, heavier weights and improved...
Phosphorous Requirement of Grower Pigs
In order to reduce the amount of phosphorous in manure to decrease environmental effects, nutrient management for pigs is crucial. By decreasing the amount of phosphorous in feed to its requirement, the amount of phosphorous excreted is reduced. Phosphorous requirements were determined to be 6.2...
Sow Bodyweight Changes in Gestation
Nutrient requirements and feeding strategies should be defined for the modern high-producing sow to increase herd efficiency. Evaluation of the factorial approach to define energy requirements was completed in pregnant sows. Sows between parity 3 and 5 can have the DE allowances predicted to maximize...
Effect of Amino Acid Intake in Gestation on Sow Performance
Maximized productivity and efficiency can be produced through re-defining amino acid requirements for high-producing sows in gestation. Nutrient requirements should be met but not exceeded. Effect of lysine levels were observed, with total intakes over 10.6 g/d (8.3 g Dlys/d) of lysine in gestation not...
Digestibility of Energy and Amino Acids in High-Oil Corn
Knowing the DE value in feedstuff can help to better formulate new diets. High-oil corn digestibility of amino acids and energy and DE content was characterized then related to chemical characteristics. Using gross energy or oil content, corn DE content can be predicted. High-oil corn...
Effect of Dietary Enzyme on Barley Energy Digestibility
Dietary enzymes can improve nutrient digestibility in barley diets. Reducing DE content differences in barley may be achieved through supplemental enzymes digesting fibrous fractions. An ingredient evaluation should be completed to increase enzyme supplementation benefits. Effect of Dietary Enzyme on Barley Energy Digestibility (full article)...
Dietary Enzyme Improves Nutrient Digestibility of Canola Meal-Diets
Non-starch polysaccharides and fiber limit the nutritional value of cereal grains and canola meal. A dietary enzyme (non-starch polysaccharides-degrading enzymes, ß-glucanase and xylanase) was studied on cannulated weaned pigs, looking at increasing nutrient digestibility. Degrading non-starch polysaccharides through supplemental enzymes improved ileal digestibility of amino...
